HEATER.

To all whom it may concern:

Be it known that I, WILLIAM Gnome GLENN, of the city of Toronto, in the county of York, in the Province of Ontario, Canada,.have invented certain new and useful 1 Improvements in Heaters, of. which the following is the specification. I

My invention relates to improvements in heaters, and the object of the invention is to devise a heater in which all the. gases and smoke will be consumed before they leave T the heater and hence produce perfect com bustion. i

A further object: is to make the heater adaptable for hot air and hot water heating.

A still further object is to produce heat at the lower portion of the heater and heat at the 1 thereby provide a maximum lower portion of the heater and also provide a more even radiating surface from the top to the bottom of the heater, and furtherconserve the heat within the heater, so asto obtain a maximum benefit in distribution.

Still further objects are to make the heater therefore, adaptof minimum height, and, able to low ceiling cellars, and to make the fire pot, such a form as will permit the use of a low and cheap grade of fuel- To effect these objects I have constructed my heater with'a fire potv having a hollow wall perforated at the lower inner ortion thereof, and a central hollow cone :1 0 per- 'forated, a cone frustum shaped top for the fire pot, and a feeding orifice leading to the fire pot, an inner wall surrounding the fire pot and extending down to the bottom of the same and forming an inner chamber, an intermediatev wall surrounding the inner wall and forming an intermediate chamber communicating with the ash pit, an outer chamber, passageways at the top connecting the outer c amber with the innermost chamber, passage-ways leading from the ash it below the fire box into the intermediate chamber and a smoke pipe leading from the intermediate chamber out through the outer chamber, and hot water coils located in the. intermediate chamber, the parts belng otherwise arranged and constructed in detail as hereinafter more particularly explained.

Figure 1, is a sectional perspective View showing my improved furnace and heater the section being taken on line 2-2, Fig. 2. Fig.2, is a sectional fplan on a plane through the up or portion 0 the fire pot on the'hne 1 -1 0 Fig. 1.

; In'the drawings like characters of referding parts in each D isthe fuel orificeand D: the door therei A. formed" between the walls A, It,will-be noticed that the inter mediate j chamber A'-.'communicates around wa'rdly extending of the ash pit being set in a Y Y I' is a closable grate, which isof a dished hollowcone provided with per- The cone is supported on the I ring J and has a pipe K3 leading from the topthereoffor the supply of fresh air.

L is a ring surrounding the fire pot and carrying, by means of the arms L, the ring L supporting the cylindrical casing L g which extends up to the top of the outer I casing A. The cylindrical casing L forms i a chamber to receive the coal where the heater is used as a self feeding stove or heater. The top of the chamber L, is, of course, rovided with a. closure L. i

The the pot wall F is .preferably made of cast iron, and the central hollow cone of fire clay, or other non-fusible materials.

The draft in my furnace is inward and downward and passes from the. fresh air conduit F through the hollow fire pot and perforations thereof and the bed of fuel contained therein inwardly and downwardly through the hollow perforated cone or chain'- ber- K into the ash pit thence upwardly through the annular chamber A and out by I the smoke pipe A The pipe K supplies the fresh air or oxygen to produce a sec- 1' ondary combustion in the chamberK, The result is that all the fixed'. carbons in the fuel and smoke are burned and the greatest heat is at the bottom of the fire pot and I heater. instead of at the top where the-coal would be placed through the fire door D if r the furnace is not a self feeding one. 7

The heat radiated from the fire pot passes I through the chambers A f and A, such chambers being connected at the bottom by apipe or pipes 3, whereby the fresh air passes inwardly into the chamber A to be heated and by the passageway A? whereby the heated air passes inwardly near the top I e of the furnace into the chamber A.

The heated air at the top of the furnace. is as hereinbefore stated carried off by thet pipes O to the different portions. of the house or buildings I J I of my hot .water It will be seen by the use coils in the intermediate rehamber. that the heat generators in thefire, potwill pass recoils, thereby serving coils, which, of course, will be suitably conleading from the lieved of the smokeand'jproducts. of combustion upwardly through the hot water to heat the hot water nected to radiators throughout the house. IVhat I claim as my invention is: 1.. In a heater, in combination, a chambered or hollow wall fire pot; having'the inner wall perforated, acommunicating pipe atmosphere .to the hollow Wall, a suitable grate and supporting ring. therefor upon which the fire pot'rests, a cen; gas combustion chamber within 1 Zral' vertical l the heater below the chamber whereby air is introduced to pass downward through the chamber producing a secondary combustion within the central chamber, and an outlet pipe connected wlth grate for carrying off the products of combustion.

2. In a heater, bered or hollow wall fire pot having the innerwall perforated, a communicating pipe leading from the wall, a central Vertical gas combustion chamber within the fire-pot and provided with suitably perforated walls, and an open bottom, and a pipe leading into the top of ,the said combustion" chamber whereby air is introduced to pass downward through the chamber producing a secondary combustion within the central chamber, pipe connected with the bottom of saidconibustion chamber for carrying off the prod ucts of combustion.

3. Ina heater, the pot arranged to' through the fuel, located secondary com ustion chamber in the firepotand open. at the bottom, and a pipe connecting. the top with the atmosphere for supplying a downward draft of i the purpose specified. n

4. In a heater, the combination with a firecoinbination with a firehave a downward draft located within the firepot. and having atmosphere to the hollowand an outlet of said chamber in combination, a charm of a erforated centrally air theret-hrough as and'for rations in 'its walls through which'the products of combustion pass, a pipe connecting the top of said chamber bottom of said chamber for producing a downward draft of air therethrough.
